Special Issue Information
Dear Colleagues,
High-frequency and ultra-high-frequency piezoelectric actuators and motors represent a dynamically evolving research frontier, garnering sustained attention due to their unique advantages: compact form factor, rapid transient response, nanometric positioning resolution, manufacturing scalability, electromagnetic interference immunity, and inherent self-locking capability under static conditions. Over the recent 5–10 years, technological advancements in high/ultra-high-frequency piezoelectric drive technologies have witnessed exponential growth, positioning them as pivotal enabling components for applications in micro-robotics, adaptive optics systems, nanoscale manufacturing, and extreme operational scenarios (e.g., aerospace navigation, deep-sea robotic exploration, and high-field magnetic environments). Despite these progresses, critical technical challenges remain, including tribological wear at contact interfaces, thermal management under high-frequency excitation, velocity instability at low operating frequencies, material aging effects, service life limitations, and system reliability under harsh conditions.
This Special Issue aims to foster interdisciplinary dialogues among academic researchers and industrial innovators, providing a comprehensive platform to disseminate cutting-edge concepts, recent theoretical insights, and practical achievements related to, but not confined to, the following focus areas:
- Innovative operating principles and structural designs for high-frequency and ultra-high-frequency piezoelectric actuators/motors, including novel vibration mode utilization and energy conversion mechanisms;
- Multi-degree-of-freedom (multi-DOF) ultrasonic motor systems integrated with high-frequency drive capabilities, emphasizing decoupling control and kinematic optimization;
- Physics-based modeling frameworks, adaptive control algorithms, and intelligent system architectures for high-frequency piezoelectric drive systems;
- Engineering applications of high/ultra-high-frequency piezoelectric actuators in extreme environments, covering thermal/vacuum compatibility, radiation resistance, and hermetic design methodologies;
- Theoretical foundations and experimental characterizations of high-frequency piezoelectric-fluid coupling vibration control, including fluid–structure interaction modeling and resonance suppression techniques;
- Microfluidic precision jetting technologies enabled by high-frequency piezoelectric actuation, addressing nozzle geometry optimization, droplet ejection dynamics, and closed-loop control for biomedical, industrial printing, and lab-on-a-chip applications.
